The black and brown spots that occur on areas that have been exposed to the sun are called age spots, brown spots, or liver spots, though they have nothing to do with the liver. Sun damage happens over time when the skin is overexposed to the sun’s rays, especially ultraviolet rays. Chronic exposure to sunlight causes abnormal pigmentation, premature skin aging, and skin cancers. Sun damage may also expose itself in the way of increased visible vascularity in the skin including general redness or visible small vessels.
Get them on a good sunscreen regimen - Then a good skin care routine -hydrafacial and perhaps laser resurfacing, chemical peels, etc.
